member this.IsFirstDisplayedRow : bool
Public ReadOnly Property IsFirstDisplayedRow As Boolean
屬性值
如果正在繪製的資料列是目前 DataGridView 中所顯示的第一個資料列,則為 true
,否則為 false
。
範例
下列程式碼範例示範此成員的使用。 在此範例中,事件處理常式會報告事件發生次數 DataGridView.RowPrePaint 。 此報告可協助您瞭解事件發生的時間,並可協助您進行偵錯。
若要執行範例程式碼,請將它貼到包含名為 DataGridView1
之型 DataGridView 別實例的專案。 然後,確定事件處理常式與事件相關聯 DataGridView.RowPrePaint 。
private void DataGridView1_RowPrePaint(Object sender, DataGridViewRowPrePaintEventArgs e) {
System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ClipBounds", e.ClipBounds );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ErrorText", e.ErrorText );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
